The major advantages that an RTD has over Thermocouples are: Stability, Precision, and Repeatability. The disadvantages are the price and response time. The following table explains in more detail.
Stability is the ability of a sensor to measure temperature with precision for a given length of time.
Repeatability characteristics of a temperature sensor represents the ability of the sensor to keep the same physical behaviour for any give temperature even though it has been used and exposed to different temperatures. In other words, it’s ability to conserve it’s stability even after many heating and cooling cycles.
